2025 Team Competition Questions Grades 9-10

Pdf Summary

The document is a confidential Math Kangaroo USA Team Competition 2025 test for grades 9 and 10. It includes 30 problems total: 20 multiple-choice questions and 10 short-answer questions, to be completed in 60 minutes.<br /><br />The multiple-choice section covers a wide range of topics, including:<br />- arithmetic and number properties<br />- geometry and area/perimeter calculations<br />- ratios, percentages, and mixtures<br />- combinatorics and counting<br />- algebra and equations<br />- logic and pattern-based reasoning<br /><br />Example problem types include finding sums of digits on cards, painting roof areas of stacked square buildings, determining values in edge-labeled pyramids, comparing jump heights as percentages of athlete height, identifying the smallest expression for a given x, and counting valid pack combinations or colorings.<br /><br />The short-answer section continues with more advanced geometry, counting, and logic problems. These include:<br />- finding the perimeter of an irregular hexagon cut from triangles<br />- analyzing bus route pass counts among villages<br />- maximizing the number of kangaroos whose ages multiply to 2025<br />- digit-reversal number properties<br />- counting parallel edge pairs in a prism<br />- determining the maximum number of liars in a region-based logic puzzle<br />- finding areas and volumes in geometric configurations<br />- counting integer-radius annuli with a given area<br />- counting valid colorings of touching hexagons<br /><br />Overall, the test emphasizes creative mathematical reasoning rather than routine computation, with many problems requiring insight into geometry, divisibility, combinatorics, and logical deduction.
